Plant cells usually can be distinguished from animal cells because only plant cells have
Answer:
A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.

Explanation:
Write the overall reaction for cellular respiration.
Answer: Explanation: Cellular respiration is the chemical reaction in which glucose and oxygen are turned into water, carbon dioxide, and energy (ATP). ... C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP is the complete balanced chemical formula for cellular respiration.
Explanation:
Answer:
cellular respiration is the process of extracting energy and is explained in 3 steps.
first step: the glucose is broken down in the cytoplasm, which is called glycolysis
second step: the pyruvate molecules are then transported into the mitochondria, the "powerhouse" of the cell
third step: The molecules are transformed chemically when it enters an electron transport chain. This allows the molecules to be turned into ATP.
Once you know this, the chemical reaction is one molecule of glucose (C6H12O6) and six molecules of oxygen (O2) yields six molecules of carbon dioxide (CO2) and six molecules of water (H2O).
C6H12O6 + 6O2 → 6CO2 + 6H2O
this creates ATP
What does it mean for a model to be "to scale", or a scaled model?
Answer:
To scale means it's the same size as in real life, as in 1 foot = one foot

Explanation:
Farmers have selected for increased oil content from corn. For a long time, the plants responded with steadily increasing oil content, but recently the response slowed and then stopped. When this line of corn is crossed to another line and the hybrids are selected, the oil content resumed its climb. What is a plausible reason for the lack of response?
A. The environmental conditions improved.
B. The genetic variation for the trait was exhausted.
C. There was too much genetic variation for the trait.
D. The environmental conditions deteriorated.
E. Artificial selection is different than natural selection.
Answer:
B. The genetic variation for the trait was exhausted.
Explanation:
Oil content is a quantitative trait, ie., a phenotypic feature that depends on the accumulative effects of many genes and the interaction of a genotype with its environment. During crop improvement, the plants (i.e., lines) containing desired alleles involved in the variation of this trait will be selected, thereby increasing oil content but simultaneously decreasing the genetic variation of the population. In consequence, after successive rounds of artificial selection, lines will not have sufficient genetic diversity to be again selected for this trait.
Which of the following statements is true?
Mitosis produces four identical daughter cells from one parent cell.
Sexual reproduction occurs much more quickly than asexual reproduction.
Meiosis creates four nonidentical daughter cells from one parent cell.
Asexual reproduction occurs when an egg cell is fertilized by a sperm cell.
Answer:
Meiosis creates four nonidentical daughter cells from one parent cell.

3. What things does your body do automatically to cool down or warm up?
Answer:
For your body to cool down one method is to sweat.
Explanation: Your sweat glands release sweat, which cools your skin as it evaporates. This helps lower your internal temperature
To keep warm your body shivers and your blood pressure decrease, it brings the blood back to the heart to keep you warm, also in you blood, your hormones create glucungons that makes the liver shoot out glucose to keep you warm. To keep cool you body sweats and in you blood the hormones create something called insulin that makes you cell take in the glucose in you blood.(Fun Fact: the things that I just said are negative feedback).

When you use the same histone protein as your standard, you determine the histone protein concentration to be 5 mg/ml. Explain the discrepancy (pick ONE answer): (5 points) a. The histone protein has fewer basic amino acids than albumin. b. The histone protein has more acidic amino acids than albumin c. The histone protein has more basic amino acids than albumin d. The histone protein contains more methionine than albumin
Answer:
A. The histone protein has fewer basic amino acids than albumin
Note: The question is incomplete. The complete question is given below:
You use the Bradford (coomassie) assay to determine the concentration of a whey protein. You use bovine albumin as your standard. You determine the histone protein concentration to be 3 mg/ml. When you use the same whey protein as your standard, you determine the histone protein concentration to be 5 mg/ml. Explain the discrepancy (pick ONE answer): (2 points) The histone protein has fewer basic amino acids than albumin. The histone protein has more acidic amino acids than albumin c. The histone protein has more basic amino acids than albumin d. The histone protein contains more methionine than albumin
Explanation:
The Bradford assay measures the concentration of proteins in a a protein sample using a color change that occurs from brown to blue when the protein in the sample binds to Coomassie dye. The Coomassie dye specifically binds to basic and aromatic amino acids in the protein. A standard curve is created using absorbance data from samples of proteins of known concentrations. The spectrophotometer is set to read at 595 nm in the Bradford assay as the peak absorbance of Coomassie Blue once bound to proteins occurs at 595 nm.
The higher the concentration of proteins, the higher the color intensity and the higher the absorbance values.
Since when bovine serum albumin was used as standard, the sample protein concentration was lesser than when the protein sample was used as standard, this means that the sample protein binds less to Coomassie dye as a standard thereby giving a higher sample protein concentration than the BSA standard. Therefore, the histone protein has fewer basic amino acids than albumin.
true or false , the mRNA codon UGG is the only codon that codes for the amino acid tryptophan
Answer:
true
Explanation:
Many of the plants in a grassland environment are specifically adapted to that habitat. The natural selection that led to this adaptation was a result of all
the following EXCEPT
populations of plants naturally exhibit variation
plants produce more offspring than can survive.
the available resources do not support all the plants,
related plant species share some genetic material.
Answer: hybridisation between related species is unlikely to contribute to adaptive speciation.
Explanation: any population has natural genetic variation. The available resources are insufficient for all plants (and conversely, not all offspring survive). Natural selection favours variations better suited to the conditions.
Although hybridisation is more common in plants than animals, and can lead to speciation, adaptive radiation from an ancestral species is the general response to environmental change, such as from rainforest to savanna. There is low probability of selective advantage from hybridisation of two ancestral species adapted to niches within the original habitat when the conditions in those niches changes significantly.
Answer:
The correct will be C: The available resources do not support all the plants.

What type of microscope is used when Determining whether a tissue type is
human, plant, or animal
Answer:
compound microscope
Explanation:
they are illuminated and the image seen with this type of microscope is two-dimensional. this microscope is the most commonly used this microscope is the most commonly used you can view individual cells even living ones
Answer:
The Compound Microscope.
Explanation:
You would use this microscope because you are examining and analyzing a tissue sample and are trying to determine if its human, plant or animal. The compound microscope enlarges things to make them look bigger. So you would use this because you would be able to see the tissue sample more clearly and bigger and then all you have to do is look to see if that would be human, plant, or animal. I hope this helped, please mark brainliest if it did. :)

In muscle tissue, what is the reactant of lactic acid fermentation and the product that builds up during intense exercise?
The reactant of lactic acid fermentation and the product that builds up during intense exercise is glucose.
Homolactic Fermentation in Muscle CellsLactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars are converted into cellular energy and the metabolite lactate, which is lactic acid in solution. Glucose is the simple sugar reactant used in this type of homolactic fermentation, instead of lactose used in the case of bacteria. This process of energy production is employed by muscle cells when oxygen levels are low, such as during periods of extreme exercise.Learn more:
